Do you mean that if a, say, “gh_worksession.gws”-file is present in a folder, then (only) that configuration of plugins will be automatically loaded. Interesting idea.
But what would happen when swapping between GH-projects in different folders? And what if if having multiple GH-definitions in the same folder?
I assume it should not unload already loaded plugins on swapping between configurations or GH-definitions, since that could wipe out values of current global variables etc.
